Suzhou REPOSAL Electronic Machinery Equipment Co., Ltd. releases precision automatic paint stripping and wire breaking winding machine

    In the inductive coil winding process, the winding process requirements of the coil are quite different.The diameter of the enameled wire varies from thin to thick, the structure of the coil varies from disk to column, and the type of enameled wire ranges from ordinary to self-adhesive wire. Therefore, for a coil winding factory that does not emphasize competitiveness, the machine required is a winding machine with a larger range of adaptation, but often a winding machine with a larger range of adaptation is for each specific specification of coil winding. Whether it is quality or efficiency, it is difficult to have targeted competitiveness.

    In order to keep our customers competitive in the induction coil winding process, we have developed this winding machine-precision automatic paint stripping and breaking winding machine in response to customer needs.

This model is mainly aimed at coils with a skeleton with a larger enameled wire diameter. It has several features, one is the fast winding speed, if it can maintain a faster winding shaft speed when the diameter of the enameled wire is larger, and the other is the winding line is flat. Through control and targeted structural optimization, a compact and consistent coil can be stably wound. Third, there is an automatic paint stripping function. For thicker non-direct welding enameled wires, adding this function is equivalent to combining two processes Integrating into one process, the fourth is to add the function of automatic disconnection.For thicker enameled wires, automatic disconnection improves efficiency, strengthens consistency, and significantly reduces the labor intensity of operators.

For details, please refer to the video. The operation beat of this video is taken during the acceptance of the machine. The entire operation process is fast and stable, but in fact, there is still room for improvement in the efficiency of fixing and dismantling the enameled wire head.

Suzhou REPOSAL Electronic Mechanical Equipment Co., Ltd. is a technology enterprise specializing in R&D and production of winding equipment. For many years, it has insisted on maintaining innovation and researching and developing products with independent intellectual property rights.

　 For quite a long time, my country's winding machine manufacturing industry generally has the problems of low technology, small scale, free and scattered production, and insufficient technological innovation of most enterprises. Compared with related industries abroad, my country currently has fewer types of winding machines and supporting equipment. The control technology used is relatively backward, and its accuracy and performance are not as good as those of their European and American counterparts. Moreover, the product has low production capacity and poor stability.

     In the face of technical gaps, Suzhou REPOSAL made a detailed market research and took the entire series of precision winding machines and Roche coil winding machines as breakthrough points.It valued cooperation with user companies and not only carefully understood the existing process requirements of customers. And through the company's accumulated technical database for many years, on the premise of no or little increase in costs, it actively provides new ideas and new solutions for customer process upgrades.In a specific single implementation case, this approach has undoubtedly aggravated us The execution cost of the company has reduced the company's profits, but this idea has been implemented and verified for a long time.In fact, our customers have tapped the potential of the coil winding process through our winding machine equipment and become our long-term cooperative customers. We have also accumulated more technical data for our research and development direction and solutions through proactive improvement of individual cases, so as to achieve continuous innovation.

      Manufacturers of small motors and coils are faced with the need to increase production capacity and improve product reliability, and they need to continuously reduce the damage to the insulation properties of enameled wire caused by coil winding and assembly. Due to the large stretch during the coil winding and assembly process, the insulating layer of the enameled wire must have good flexibility, and the enameled wire should also have good formability (softness of the wire).

        1 The formability of the enameled wire The mechanical properties of the enameled wire are divided into the mechanical properties of the conductor and the paint film. In the process of winding the enameled wire, in the wire embedding process, and in the electrical products using the enameled wire coil as a component, mechanical stress acts on the enameled wire during operation, so the enameled wire may be elongated and the paint film is damaged. etc. phenomenon. Therefore, enameled wire has the requirements of elongation, rebound angle, softness, tensile strength, paint film elasticity, paint film adhesion and scratch resistance.

        1.1 Mechanical properties of conductors: softness, elongation, rebound angle, and tensile strength.

        Elongation reflects the plastic deformation of the material and is used to assess the ductility of enameled wires. The springback angle and softness reflect the elastic deformation of the material and are used to evaluate the softness of the enameled wire. The tensile strength is related to the recovery recrystallization degree of the conductor and the grain size of the recovered tissue. The tensile strength, softness and elongation reflect the quality of the copper material and the degree of enameled annealing, which have a great impact on the quality of the winding. great relationship.

        In the process of enameled wire coating, if the number of paint passes and the number of loops is too large, and the diameter of the guide wheel is not large enough, the wire will be continuously deformed by alternating tension and compression, resulting in the distortion of the lattice. It breaks easily when stretched. When the enameled wire is running, the wire is subjected to excessive tension, which will make the wire thinner. At this time, due to the displacement of atoms or ions on the lattice due to sliding, residual internal stress has been formed, so the wire is brittle and elongated. rate and softness rate decreased.
